This method features three important improvements over existing approaches: First, the Wigner\u2013Ville distribution (WVD) is used to better estimate the nonstationary analog channel frequency response (ACFR) spectrum. Secondly, the estimated ACFR spectrum is approximated with a rational polynomial model using the [Formula: see text]-norm metric. The corresponding [Formula: see text]-norm minimization problem is solved using a primal-relaxed dual global optimization (PRD-GOP) method. Thirdly, the digital compensation circuitry is designed utilizing a preconditioned biconjugate gradient stabilized (BICGSTAB) algorithm that yields a computationally efficient solution. Numerical experimentations have been conducted and the outcomes validate the feasibility and superior performance of this proposed method. <\/jats:p>","DOI":"10.1142\/s0218126619501342","type":"journal-article","created":{"date-parts":[[2018,8,21]],"date-time":"2018-08-21T03:07:46Z","timestamp":1534820866000},"page":"1950134","source":"Crossref","is-referenced-by-count":7,"title":["Digital Estimation and Compensation of Analog Errors in Frequency-Interleaved ADCs"],"prefix":"10.1142","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3374-3113","authenticated-orcid":false,"given":"Jinpeng","family":"Song","sequence":"first","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, 2006 Xiyuan Ave., Chengdu 611731, P.\u00a0R.\u00a0China"},{"name":"Department of Electrical and Computer Engineering, University of Wisconsin-Madison, 1415 Engineering Drive, Madison 53706, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shulin","family":"Tian","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, 2006 Xiyuan Ave., Chengdu 611731, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Hen","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Wisconsin-Madison, 1415 Engineering Drive, Madison 53706, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, 2006 Xiyuan Ave., Chengdu 611731, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuojun","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, 2006 Xiyuan Ave., Chengdu 611731, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lianping","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, 2006 Xiyuan Ave., Chengdu 611731, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wentao","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, 2006 Xiyuan Ave., Chengdu 611731, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2019,7,29]]},"reference":[{"key":"S0218126619501342BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/ISCAS.2006.1693352"},{"key":"S0218126619501342BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.1980.1051512"},{"key":"S0218126619501342BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/19.153341"},{"key":"S0218126619501342BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2005.856195"},{"key":"S0218126619501342BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2016.2585640"},{"key":"S0218126619501342BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2017.2665983"},{"key":"S0218126619501342BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2018.2829762"},{"key":"S0218126619501342BIB009","doi-asserted-by":"publisher","DOI":"10.1109\/TFSA.1994.467350"},{"key":"S0218126619501342BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/78.668549"},{"key":"S0218126619501342BIB011","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2014.2331961"},{"key":"S0218126619501342BIB013","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2006.882224"},{"key":"S0218126619501342BIB014","doi-asserted-by":"publisher","DOI":"10.1109\/I2MTC.2018.8409544"},{"key":"S0218126619501342BIB015","doi-asserted-by":"crossref","first-page":"2022","DOI":"10.1109\/ISCAS.2013.6572268","volume-title":"2013 IEEE Int.
